Abstract

An environment for radiation shielding analysis for manned deep space mission scenarios has been developed. The analysis is performed by dividing a mission scenario into three possible different phases, namely the interplanetary cruise phase, the final planetary approach and orbit insertion, and the surface phase. In the first phase only Galactic Cosmic Rays and Solar Events particles are used, in the second phase the effects of trapped radiation belts are also taken into account, and in the third phase also the effect of the planetary environment is considered. Planetary surfaces and atmospheres are modeled based on results from the most recent targeted spacecraft. The dose results are coupled with mission design visualization techniques.
